TO ALL WHOM IT MAY OONOERN:

Be it known that 1,'JOHN J. PnLLETT, of Oconomowoc, in the county ofWaukesha, and State'of Wisconsin, have invented a new and improved Gate;andvI do hereby declare that the following is a full,.clear, and exactdescription of the construction and operation ot' the same', referencebeing had to the annexed drawings, making a part of this speciiication,in which- Figure 1 is a side elevation.

Figure 2 is a cross-section.

This invention relates to the class of farm-gates which are expanded andcontracted longitudinally in order to close or open them, by means ofthe device known as Jacobs Ladder, and consists in enclosing said ladderbetween the bars of a sliding frame, by which the gate is greatlystrengthened, and at the saine time rendered 'l more beautiful inappearance.

In the drawings, ct a represent the Jacobs ladder; B, the post againstwhich the gate closes; C, the post to which it is hung; D D,guide-posts, of any suitable height; E E, posts that support the shaftby which the gate is opened or closed; F, the shaft referred to, havinga pulley, G, and an arm, H, attached to it, and I a cord, passing onceor more around the pulley or wheel G, to one point on the rim of whichit is fastened ,to prevent slipping, and having its ends attached to theextremities of the gate. By turning the crank in one direction, the cordI draws the gate to the right, as seen in fig. I, and leaves the wayopen; and by turning the crank in the opposite direction, the gate isforced tothe left and closed. The arms HH are conneted together by arod, 7L, and are attached to the shaft by a loose joint, which permitsthem to be roclied to the right or-left, as seen by the blackand redlines in g. 2. By this means the gate may be securely locked whenlclosed, it being only necessary to bring one of the arms H H behind andin contact with a pin or projection, h', fixedto one of the posts E E.The projection t may be in the form of a hook, if desired, whereby itwill more securely hold the arn1,'and the side opposite to the concavemay be bevelled or inclined to facilitate the locking of the device. Itwill only be necessary to provide one locking-pin or hook, as the armscan both be operated from either side of the gate by means of theconnecting-rod 71,. .y

The bar a, which. at its lower end is pivoted to the postv C, isattached at said pivot by a xed hinge, c. The bar in connection with it,that is pivoted at its top to thesame post, is hinged to said post bymeans of a pivoted arm, m, one end of which is attached to the post, andthe other to the bar n, as seen in tig. l. As the Jacobs ladder isexpanded or contracted in length, the position of the two bars connectedto post O will be changed, sometimes being more and sometimeslessvertical, and the arm m will rise and fall, accommodating itself to thischange of position.

The main feature of the invention, however, consists in providing anenclosing-frame, composed of the upright standards S- S', the latteroutside of the post C, and the fermer inside of the post- B, unitedtogether by longitudinal rails T 'I1 T2, which extend from standard tostandard, on both sides of the ladder,henclosing it betweenthem. A pin,T, passes through the middle rail T1, and the two bars a a, that standadjacent to theA standard S, that being the only point at which theladder is connected with the enclosing-frame. The ends of the cord I areattached to the standards S S, and slide the enclosing-frame back andforth, the ladder inside of the frame contracting or expandinginproportion to the movement of the frame.

I am aware that gates havefor many years been constructed on the Jacobsladder principle, but without the enclosing-frame. They have thereforebeen weak and easily racked out of position, besides being liable to getout of repair. By the use of the frame, however, the gate is greatlystrengthened and supported, besides being rendered more agreeable to theeye. I do not broadly claim theuse of such ladder, but

What I do claim as my invention, and-desire to secure by Letters Patent,is-

I. The combination of the pivoted bars a a with the enelosingframe S S T'lL T1, when operating substantially as and for the purpose set forth.

2. The combination of the arms H H, connecting-rod il., and locking-pinit', when used in connection with a sliding gate, asabove described, andwith the wheel and cord for opening und shut-ting it, as a device forsecurely locking said gate, in the manner described.

To the above speciiication of my improvement, I have signed my hand,this eighteenth day of February, i868.

JOHN J. IELLETT.
